Week 4 Challenge : CFD Meshing for BMW car

AIM:

To generate CFD meshing For BMW car and volumetric mesh for wind tunnel with ANSA software for given mesh constrain.

Procedure:

Step 1: Generate Ansa file which is given along with challenge.

Step 2: Go to checks for detecting geometrical error.

Step 3: Split the model into half portion by the help of symmetry plane.

Step 4: Clean the geometrical error with the help of topology tools.

Step 5: Assign PID for all the components separately.

Step 6: Assign the quality criteria for each and every PID’s

Step 7: Go to surface mesh.

Step 8: Then go to mesh parameters change the target length accordingly to separate constrain given to PID’s and surface mesh every PID’s accordingly.

Step 9: By using transform tool another side of the car is mirrored.

Step 10: After surface meshing of the car model. Create a Wind Tunnel for CFD Analysis.

Step 11: For Wind Tunnel surface meshing has been carried out.

Step 12: volumetric mesh has been done successfully using Tetra CFD mesh for the Wind Tunnel area.

Learning outcomes:

• Advanced topology cleanup.
• In this module, I have learned about symmetric operation of a model.
• Solution quality failure of the element in the quality criteria
• How to create a Wind tunnel using ANSA
• Volumetric meshing for the created wind tunnel.

Result:

Thus, the CFD meshing For BMW and Volumetric mesh for wind tunnel are generated successfully.

Conclusion:

I have studied the different types of tools used in the geometric error clean up and Quality criteria setup during the challenge completions of CFD meshing for BMW.
